WATER-FILTER.

Specification of Letters Patent. Patented. 1 920,, jglfi Applicat'ion filed April 11; 1916. FS'eriaPNo; 90337.

To all whom z'tmay concern Be it' known that LHENRYL-KUENZLI, a

citizen of the'United Statesyand a resident of Nevada, in' the county-0f Wyandot and State of Ohio, have invented a new and useful'Improvement in'VVater Filters, of which the followingis a specification.

the water during its passage and for removing sediment of all character from the water,

and wherein the 'saidremoving means is so arranged thattheaction of the water coming on to the said means-will clean the sediment from the cleaning means and deliver it outside the pipe.

In the drawings: Figure 1 isa-perspective view with. parts of the casing broken away to show theinternal structure, 'Fig. 2 is a verticalsectiom-Figs. 3, 4: and 5 are sections on the-lines 33, 4-4, and 55, respectively, of FigJQjFig; 6 is adetail perspective view of the lower end of the screen, and

Fig. 7 isa section on the line'7,7 of Fig. 1.

The present embodiment of the invention comprises a casing 10 of approximately rec tangular cross section having a top 11 substantially pyramidal in shape, and a. hoppershaped' bottom 12 as-shown,for permitting the'easy escape of the 'waterfrom the filter.

The bottom '12 .isprovided with a central opening and a "SllOlt pipe 16 extends from the opening, the pipe seotion having its inner end flanged within the bottom 12 A to maintain the same in position, and the pipe section is attachable toa part of the cistern supply pipe.

The top llhas an opening near the rear wallof the casing, and the inlet pipe section l 17 extends through this opening, the said section being 'crimp'ed orwbeaded as shown at 18 to receive the edge of the opening, and the lower end ofthe: pipe'se'ctionis beveled as'shown at 19, terminating in a down- .wa-rdly extended lip 20. '-'The lip 20 isat the: front of the pipe section, and itwill be 110 01066. from an inspection of Fig. Qthat the said lip inclines rearwardlyfor a. purpose to be later described.

The openin gin the topll for the pipe section 17 is at the highest part of the said top, and the edges 12 of the top extend to the corners of the casing, the crimp connection between the body and-"the-top indicated at 15 lIl Fl'g. 2,form1ng a material reinforcement at these points. The front wet-1122 of the casing is'provided with a -substantially rectangular opening =23 intermediate. the ends of thecasing and; near the lower end,

and the openingis reinforced by a frameQ l of wire or the like, the said wire being held in beads 25 formedfrom thematerial of the casing at the opening. a

A screen is arranged between the inlet'and the outlet with its lower end at the opening 23, the upper end of the screen being near the top of the casing and at the rear wall,

while the lower end'is at the lower end of the opening 23. The screen26 -is formed from heavy'wire cloth of suitable-mesh and preferably of considerable strength,"in order to withstand the impact of foreign bodies that might enter the casing through the inlet 17 The opposite sides. of: the screen are flanged forwardly as indicated at 26 and theseflanges extend from the lower end to near the'"*upper end, and the upper end is 'bent'at a slight angle to the body of the screen as shown at 28 to rest flat against the inner face of the rearwall. The lower end of the screens-is bent in't'he same direction as the flanges 26* as indicated at 27 and this flange 27 rests upon the lower edge of the opening 23, and upon the beadwhich incloses the frameQ i at this point. The ends of the'flange 27 are soldered to the adjacent ends of the flanges 26 'as indicated in Fig. 6.

The screen 26 is supported-and braced at about its center by a cross rod31, connected with the opposite-side walls of the casing.

This rod asshown has its ends threaded a'nd passed through openings in the I walls,--and lock i uts are threaded o t t e ends "on The divider 29 depends behind the rod 31 and it is of a width to extend some little distance below the rod. The solder is so placed with respect to the divider that the reticulated material of the strip is converted into a substantially imperforate plate. The divider is in fact a solid body, being formed from the same material as the screen for purposes of convenience. At its lower end a deflector or divider 32 is arranged, the said deflector or divider being formed from a strip of the same material as the screen and secured thereto by means of solder or the like, and this strip is converted into an imperforate plate by means of the solder from its connection to its free edge. This divider 32 extends some distance below the flange 27, and below the lower edge of the opening 23 when the screen is in place and the central portion thereof, that is, all of the said portion except the extremities is separated from the said extremities and bent downward and backward as shown at 32', in order that when the screen is in place this portion 32 will be spaced apart from the front wall of the casing and only the ends 32 of the said portion will engage the said face of the casing. These portions 32 prevent outward movement of the screen through the opening by their engagements with the front wall, and pins 33 are an ranged in rear of the screen for preventing rearward movement of the lower end of the screen.

The pins 33 are connected with the 0pposite side walls of the casing, and they are so placed that when they engage the rear wall of the screen the portions 32 will. fit against the inner face of the front wall below the opening 23, and the flange 27 will rest upon the lower edge of the said opening. The purpose of the divider 29 is to prevent the passage of the water down the full length of the under surface of the screen and to deflect the said water downward from ofl the screen, in order that the lower portion of the screen may not be clogged by such water. A great portion of the water that falls from the pipe 17 on the upper part of the screen will pass through the screen, and during a heavy flow, unless some means were provided to prevent, a portion of the water passing directly through would flow down the rear side of the screen and would hinder the passage 'as is the divider apart of the portlon 32324 from the front of the excess water through the lower part of the screen. With the deflector 29 however, the water cannot flow beyond the same and will pass down and drop off the free edge of the device.

The water passing beyond thedeflector 29 on the screen might flow out at the open ing 23 in certain circumstances were not the element 3232 provided. This deflector 32 32 causes the water passing down the rear of the lower part of the screen to b deflected into the casing instead of passing out over the flange 27. It will be noted from an inspection of Fig. 2 that the solder 32 which connects the strip 3232 to the screen extends through the body of the screen at'the upper end of the said strip 32 32*, forming a species of divider at this point on the forward or outer face of the screen.- This solid portion is extended on to the flanges 26 and its purpose is to divide the water on the front of the screen from that on the rear and that on the rear of the screen will pass down over the deflector 32--32". That on the front of the screen may pass downward through the flange 27 which is perforate and not solid 32-32 The spacing of the casing prevents any clogging or collection of water at this point, and since the the splash board is of such length that it will engage the screen below the rod 31. The lower free edge of the board is curved rearwardly slightly as shown, and when the screen is taken out for any purpose the rod 31 will limit the rearward swinging of the plate 3a and the rod will hold the plate or board in such position that the screen cannot be inserted without lifting the plate out of the way. The solder 30 which con nects the divider 29 to the screen extends to the front surface of the screens and acts as a divider to divide the water on the rear of the screen from that on the front of the screen in the same manner as the solder at The splash plate 34: is of a width approximately equal to that of the casing and the lower end of the plate normally hangs in contact with the front of the screen or nearly so.

The free edges of the upturned sides 26 of the screen fit against the side walls of he casing and the upturned edges or flanges thus in addition to their function of reinforcing the screen serve the additional function of leading the Water downwardly may be withdrawn.

1 1:; resgaso fromthe side edges of the screen toward the body. The said side edges also *defiect foreign bodies on to the body of thescreen and prevent "them i from becoming caught at the-side-edges.

The screen may be removed when desired by pushing upward on the lower end. The

portion 28 ofthe screen slips up between the. inlet pipe 17' and the rear wall'of the 'engagementof the portion -32"* 32 and when the lower end of the screen is-lifted screena sufficientdi'stance' to permit the -disthrough the opening 23 the entire screen In removing "the screen, the strip 29 is of less width than the strip 32"-'32 so that thelower end of "the screen cannot become disengaged Without disengaging also the divider '29 from the rod 31.

The length of the screen is'such' and the pins 33 are so'arranged that the-screen cannot be lifted high enough in the casing to permit [the portion 32 of the strip 3232 to move'rearwardly of the pins 33. The portion 2S of the screen will engage the top of' the casing before this disengagement may take place. The inlet pipe 17 is so arranged with respect to the casing that it forms'a lock for the upper end of the screen when the screen is in place, that is, theportion'28 of the screenfits in behind the inlet pipe and between the same and the rear wall ofthe casing as shown more-particularlyin Fig. 2.

The entire'device may be attached to any suitable support by attaching eyes 36 and 36-. "These eyes 36 have shanks 38 which extend through openings in the top 11 and at therear cornerspf the casing and each shank isbentlaterally forward as shown in Fig. 7, and is soldered 'to'the" inner face of 't 1e top. The lower eyes "36 have straight shanks which are passed through openings in the bottomatthe rear corners and soldered into place as indicated at 37. 'The'shanks 38 of the eyes 36' are 'bentforwarc'lly in order that they may not interfere with the top ofthe screen. The -bend also gives additio-nal'str'ength since the bent portion of the shank engages'beneath the top 11.

In use, when water fiows'through the inlet into the casing it" falls upon the screen near its upper end, and the greater portion of the water passes through the screen directly.

. Anyforeign bodies, as'for instance, leaves,

trash, and the like, cannot pass through the meshes of the screen, and'they are held on the upper face' thereof and washed downwardly by the fall of the Water onthe screen. The inclination of the screen is such that foreign bodies will not cling to the screen to clog the same and to prevent its proper operation. Such bodies will'be immediately wvashed down *by the falling water and will-pass out at the'opening 23 over the port-ion 27, being thus separated from the water and discharged-(')utside' of the casing. Since thewater' that 'fallsduring' coldweather is the most/"desirable for storage, adeVice' of'thecharacter .in question to be thoroughly efficient-must act in cold weather as well as in warm weather I and must not be so arranged that the water will collect therein to freeze and to thus impair the usefulness'of the filter. It 'isnot diflicult to separate the foreign bodies from the-water, but they must-also be discharged outside, in order torprovide'a'mechanism thatwill act automatically without'anyat- *-tention whatever.

The improved filter will act indefinitely without the slightest attention after it has been. once placed, all of the foreign bodies being discharged outside of the mechanism,

-while the water passes into the place of storage, no part thereof remaining in" the casing or its connections; The splash plate 34 prevents any water that might rebound from the screen when it first strikes thereon from fiying out at the opening 23. Anywatier that might rebound will strike the inner'face of the splash plate and will "flow down the same and will be turned back "upon the body of the screen by the lower end thereof. -Thisplate offers no resistance to the "downward passage of the foreign'bodies. Were such bodies of too great dimensions ,topass' between the free edge of the plate an'dthe screen, such bodies would swing the plate forwardly to permit them to pass. Itwill be noticed that the lower end of the splash plate is just below the 'upperendof 'the opening 23. The plate ho-wever,is of such lengthand, so arranged that when the lower end thereof swings forwardly it will engage the front casing wall at the upper'end of theopening, so that the plate, even when in its most forward position,-will not diminish the extent of the opening.

The screenis selfcleaning, all the foreign bodies of every character being discharged outside of'the casing, while the water isdisate it's ends, a screen arranged within the casingbetween' the inlet and the outlet and extending from the rear .wall' of the casing near the top to the lower end; of the opening, said screen being of perforatematerialand having itsside edges bent laterally andforwan-11 atan obtuse angle to the body of-the screen from near the lower end to near the upper end, the upper end of the screen being bent to lie flat against the rear wall of the casing, the lower end being bent forwardly to extend through the lateral opening at the lower end thereof, said screen having an extension extending downwardly in the plane of the screen and engaging the interior of the casing below the lateral opening, the casing having inwardly extending pins below the lower end of the lateral opening for engaging behindthe extension to hold the lower end of the screen in place, said screen having an imperforate portion extending transversely thereof above the junction of the bent lower end with the body'of the screen, said imperforate portion being spaced above the junction between the laterally bent portionand the body of the screen at the front of the screen, and extending downwardly on the rear face of the extension to a lower level than at the front of the screen.
